MOLDING-MACHINE FOR CONCRETE BURIAL-VA'ULTS.

Application sied october 27, 191s.

To all whom it may concern.'

Be it known that l, F RANK J. FFIFFNER, a citizen of the United Statesof Jkineiica, and a resident of Waterloo, Blackhawk county, lowa, haveinvented certain new and useful improvements in Molding-Machines forConcrete Burial-Vaults, of which the following is a speciication.

My invention relates to improvements in molding machines for concreteburial vaults, and the object of my improvement is to furnish a moldformed by separable parts and detachably supported in an inclosing rackor frame, the latter being supported on trunnions pivotally so that itmay be rocked vertically. This object 1 have accomplished by the meanswhich are hereinafter described and claimed, and which are illustratedin the accompanying drawings, in which:

Figure 1 is a side elevation of my improved molding machine for concreteburial vaults. Fig. 2 is another side elevation of said machine showingthe mold-casing, its core, and the inclosing rack or 'frame with thebearings of the trunnions in longitudinal vertical section. Fig. 3 is atransverse vertical section of said machine. Fig. 4: is an elevation ofthe inner face of one of the solid ends of the inclosing rack or frameof said machine as sectioned away from the rest of the racktransversely. Fig. 5 is an outside end elevation of the part shown insaid Fig. 4.-.

Similar numerals of reference denote corresponding parts throughout theseveral views.

1t is my principal object to provide a molding-machine in which the opentop concrete casket may be formed in an inverted position forconvenience in the making, and so pivotally mounted in supportingstructures as to be able to be rocked over or reversed in position forthe purpose of removing said molded casket when desired. With this endin view, I provide up right posts 31 spaced apart horizontally and fixedon transverse beams 33 and connected longitudinal beams 23, said partsbeing further connected by braces 2.1. The uprights 31 are provided withhorizontally-alined orifices in which are seated the bearing sleeves 1S,having face plates 17 secured to the uprights. An open sided rack orframe has solid ends built up of two layers of Speciiication of LettersPatent.

planks 15 and 26 secured together in rectan gular form, and whosecorners are ixedly connected to the ends of the four longitudinal beams14 by means of the cross-rods 20 and 27 secured by nuts 30. The ends ofsaid beams lll are further secured to the ends oit' said rack by meansof the bars 32 fastened on the outer heads 15 by screws or bolts. Theheads 15 are oriticed in line with the bearings 18 to receive thetrunnions or pivots 19, which are secured in the circular faceplates 16on said heads. r1`he said rack or frame is therefore mounted so that itmay be rocked vertically. The longitudinal beams 14- are connected bycross-beams 12 and the ends of the latter are detachably securedtogether by bolts 13.

rFhe numeral 28 denotes an outer box, whose bottom 25 is supported oncross bars 24 on the lower pair of the longitudinal beams 14. rThis boXis closed at the sides and bottom, but open at the top, and within it isplaced a mold-casing 1, also closed at the sides 2 and bottom 10 andopen at the top. Within the mold-casing 1 is placed a core made up ofsectional parts i and 5 for the sides, and 9 for the ends thereof, whichparts are detachably connected together by means of the sockets 7 andbars 8, detachably secured therein across vertical bars 6 on said parts.The sides and ends thus formed are spaced apart from the inner walls 1and 2 of the outer wall-casing, and both the said mold-casing and floormay be supported on a rectangular pallet such as shown at 35, whichpallet is channeled to provide a desired configuration to the upperedges of the burial vault or casket to be formed in said mold, andstrips 34 adjacent and secured to the bottom 10 serve to form therabbeted joint for the Flange of' the cover.

The numeral 3 denotes a movable cover or top for the said core, andwhich is spaced from the upper open edges of the sides and ends 1 and 2of the outer mold-casing. The outer boX 28 is held together bylongitudinal bars 29 connected by cross-rods 30, while the bars 14- atthe sides are further connected and supported by means of the verticalbeams 11 connected by means of cross-bars 36. All of these parts aredetachable from each other and can be easily assembled or disassembled.It is more convenient to form a hollow casket body upside down, and

therefore, the mold-casing and its inner core shown are supported in thetiltable rack in that position. The concrete casket is formed in theinterspaces of the mold-casing and its core in a well known manner, byfilling such spaces with the concrete, and leveling off at the top overthe open upper end of the outer easing 1. When the concrete of themolded casket has properly set, the outer casing 2S and the casing 1 aretaken away, then the casket is blocked or shored between the beams 14,the rack inverted, a support placed under the inverted casket, then theplanks 24; and 25 as also the bottom 10 with the pallet 35 removed, andthe detachable sections 4c of the core separated and withdrawn byremoving certain of the bolts 8. rlhe casket may then be lifted from therack.

It is evident that various changes in the form, construction and detailsof this device may be made without really departing from the scope andessential principles of my invention. y

Having described my invention, what I vaults, comprising spacedrelatively fixed 1 supports, a separable rack pivoted to and betweensaid supports, an outer mold-casing mounted removably in said rack, anda core formed of detachably-conneeted sections detachably mounted insaid casing in spaced relation to parts thereof.
